Putting on the boot cover is a two person job for us. What we do, however, is leave one of the back snaps "unsnapped" and then the whole procedure only takes a few minutes. The cover stays on--at a spirited speed--without any problem, too.
BTW, we only use the cover if we plan to be on a medium to longish drive. If we're just around town, we can't be bothered...then it stays at home

 

On my 05 the boot cover fits ok but i never fold it up and I don't mess with it in colder weather(like now in ann arbor).

The vibration some have commented on might be the one or both of the elastic straps. Try putting a full twist on them before snapping in place. Worked for me.

 

What is this boot for?

I got mine with the car, it was taking space in the trunk, so i just threw it in the closet ...

 

Where it will probably remain...
